Fragments from the Lost Writings of Irenæus

As therefore seventy tongues are indicated by number, and from dispersion the tongues are gathered into one by means of their interpretation; so is that ark declared a type of the body of Christ, which is both pure and immaculate. For as that ark was gilded with pure gold both within and without, so also is the body of Christ pure and resplendent, being adorned within by the Word, and shielded on the outside by the Spirit, in order that from both [materials] the splendour of the natures might be exhibited together.
